At least one delineation can be disposed on the corner that is oriented in a first direction. At least one delineation can be disposed on the corner that is oriented in a second direction, where the second direction forms an angle of 30° or more relative to the first direction.

BACKGROUND Field

Embodiments described generally relate to shipping boxes or containers having adjustable depths.

Description of the Related Art

Shipping containers come in varying sizes and shapes. Some containers have preformed delineations, such as scores, cuts, slits, or perforations that allow a user to more easily tear away an upper portion of the container that is not needed to accommodate the size of its contents. There is a safety concern with these containers, however, because the user typically cuts along the preformed delineations with a sharp blade or “box cutter” to provide a desired height. Another issue with these types of adjustable containers is that these preformed delineations are a point of weakness. So if not used, the preformed delineations can tear or release during transportation, allowing the contents of the package to spill or otherwise expose the contents within the container.

SUMMARY

In at least one specific embodiment, an adjustable container is provided that can include a body having at least two sides forming a corner therebetween. At least one delineation can be disposed on the corner that is oriented in a first direction. At least one delineation can be disposed on the corner that is oriented in a second direction, where the second direction forms an angle of 30° or more relative to the first direction.

In at least one embodiment, a box having an adjustable depth is provided that can include at least four vertically oriented sides, a top panel, and a bottom panel. A vertically oriented corner can be formed between every two adjoining sides. At least two generally vertical delineations can be disposed on each corner. At least one delineation can be oriented at an angle of 30° or more relative to the vertical delineations can be disposed on each corner beneath the at least two generally vertical delineations.

In at least one other embodiment, a panel board for making an adjustable container is provided that can include a paperboard substrate having at least one fold line formed thereon. At least one delineation can be oriented in a first direction and disposed on each fold line. At least one delineation can be oriented in a second direction beneath the at least one delineation oriented in the first linear direction, where the second direction can form an angle of 30° or more relative to the first direction.

DETAILED DESCRIPTION

FIG. 1 depicts a three-dimensional view of an illustrative adjustable container 100, according to one or more embodiments. The adjustable container 100 can include a body 160 having at least two sides (four are shown 142, 144, 152, 154) with one corner formed therebetween any two adjoining sides (four corners are shown 101, 103, 105, 107). The adjustable container 100 can further include at least one preformed delineation 120 (“first delineation”), such as a score, cut, slit, slot, perforation, or other point of weakness that is oriented in a first direction and located in at least one of the corners 101, 103, 105, 107. At least one other delineation 130 (“second delineation”) can be oriented in a second direction in the same corner as the first delineation 120. The second direction can be angled, generally perpendicular, substantially perpendicular, or exactly perpendicular to the first direction. The second delineation 130 is angled relative to the first delineation (s) 120 to serves as a stop or limiter to prevent unwanted tearing of the corner.

The first one or more delineations 120 can be straight or generally linear and run generally parallel to one another within the corner. The one or more second delineations 130 also can be linear or can be curved, including c-shaped or u-shaped. When the second delineation 130 is linear, the second delineation 130 can be oriented in a second direction that is angled relative to the first direction of the first delineation 120. For example, the second delineation 130 can form any acute angle, right angle, or obtuse angle with respect to the first direction of the first delineation 120. In a specific embodiment, the second direction of the second delineation 130 forms an angle 132 that is 30° or more relative to the first direction of the first delineation 120, as depicted in FIG. 1A. The angle between the first direction and the second direction of the delineations 120, 130 also can be 45°, 60°, or 70° or more. The angle between the first direction and the second direction also can be −30°, −45°, −60°, or −70° or more. Additionally, the second delineation 130 can curved, c-shaped or u-shaped. As mentioned above, the angle between the one or more first delineations 120 in a first direction and the second one or more delineations 130 in the second direction creates a stop or limiter to prevent unwanted tearing of the corner.

Each delineation 120, 130 can be formed partially in the body 160 or completely through the body 160 of the container. The depth of each delineation 120, 130 can be the same or the depth of each delineation 120, 130 can vary.

Any suitable number of delineations 120, 130 can be used. The pattern and frequency of the delineations 120, 130 can vary. For example, the adjustable container 100 can have a first section or set 122 of 2 to 5 or more delineations 120 above first delineation 130, and a second section or set 124 can have 2 to 5 or more delineations 120 below a second delineation 130. Any suitable number of sections can be used, depending on the original height/depth of the container. The length of each delineation 120 also can vary in each section, as well as the number of delineations 120 in each section. Further, each delineation 120 within each set or section 122, 124 can be equally spaced or not.

The adjustable container 100 can also include at least one scoreline or folding line (four are shown 172, 174, 176, 178), disposed along the interior and/or exterior of side 142, 144, 152, 154 of the adjustable container 100. The folding line 172, 174, 176, 178 can be positioned and spaced in alignment with the delineations 130 at various depths. The folding lines 172, 174, 176, 178 can create a top flap of appropriate size if folded over.

The adjustable container 100 can include a variety of container styles, including, but not limited to, a partial die-cut container or a multi-depth regular slotted container (RSC). For example, the multi-depth RSC can be a box style container created from a single sheet of corrugated board. The sheet can be scored and slotted to permit folding. Flaps (e.g., 102, 104, 106, and 108) extending from side panels (e.g., 142 and 144) and end panels (e.g., 152 and 154) can form the top and bottom (e.g., 110) of the box. The two outer flaps (e.g., 102 and 104) can be one-half the container's width in order to meet at the center of the box when folded.

Shorter containers may not require much height adjustment so fewer delineations 120, 130 may be used. Conversely, taller boxes may utilize numerous delineations 120, 130 that are spaced about to provide greater selectivity, flexibility, or both.

The delineations 120 provide a point of weakness so the corner 101, 103, 105, 107 of the adjustable container 100 where the delineations 120 are located can be readily torn by hand. The delineations 130 significantly reduce or prevent unintended tearing of the container 100 during use, and can provide a guide to provide two or more containers having a consistent height or depth. The delineations 120 can reduce or eliminate the safety risks of using a box cutter, such as an X-ACTO® knife, or other sharp instrument to adjust the height of the container. Although, for higher strength or thicker boxes, stronger delineating may be desired and optionally a knife or other suitable device may be used. The adjustable container 100 can decrease postal shipping costs by decreasing the size of the container, if a smaller container is more desired. The adjustable container 100 can also decrease or eliminate the need for inner packing to restrict its contents from moving during transit if the container is too large for its contents.

In some examples, the adjustable container 100 can be utilized without decreasing the depth. For example, if the desired depth does not require decreasing the initial depth of the adjustable container 100, the top flaps 102, 104, 106, 108 can be folded, closed, and sealed with a sealing tape or glue to form a first container depth. In some examples, the adjustable container 100 can be assembled into the desired depth by separating or tearing apart at least one set, or an uppermost section, of the delineations 120 down to at least a first delineation 130 to form a second container depth. The depth of the adjustable container 100 can be further decreased by separating at least two uppermost sections, or a second set, of the delineations 120 down to at least a second delineation 130 to form at least a third container depth.

In some examples, the delineations 130 can have a length×width dimension of at least 0.25 inches×0.0625 inches, at least 0.375 inch×0.075 inches, at least 0.50 inch×0.0875 inches, at least 0.625 inches×0.1 inches, at least 0.75 inch×0.1125, at least 1 inch×0.125 inches, at least 1.25 inches×0.1375 inches, at least 1.375 inches×0.150 inches, or at least 1.50 inches×0.1625 inches. In other examples, the delineations 130 can have a length×width dimension of less than 0.25 inches×0.0625 inches. In some examples, the adjustable container 100 can have a set or section of delineations 120 that includes at least 2 delineations, at least 3 delineations, at least 4 delineations, at least 5 delineations, at least 6 delineations, at least 7 delineations, or at least 8 delineations. The size of each delineation 120 can vary and can have a length x width dimension of at least 0.25 inches×0.0625 inches, at least 0.375 inches×0.075 inches, at least 0.50 inches×0.0875 inches, or at least 0.625 inches×0.1 inches. In other examples, the dimensions of each delineation 120 can be less than 0.25 inches×0.0625 inches.

In some examples, the at least one delineation 120 can be oriented in a first linear direction that is substantially vertical, and the at least one delineation 130 can be oriented in a second linear direction that forms an angle of 30° or more relative to the first linear direction. The first delineation 120 can include from at least 2 to at least 10 delineations arranged in series. In some examples, the first delineations 120 can include from at least 2 to at least 10 delineations 120 arranged in series, and the second delineation 130 can be located beneath the lowermost first delineation 120. Each delineations 120, 130 can partially or completely penetrate the thickness of the corner 101, 103, 105, 107, depending on the overall height and thickness of the container.

The adjustable container 100 can have any dimensions. For example, the length, width and/or height of the adjustable container 100 each can range from about 2 inches, 3 inches or 4 inches to about 10, 12, or 25 inches. In certain embodiments, the dimensions (length, width and height) of the container can be about 7 inches×4 inches×3.375 inches; at least 9 inches×6 inches×5.625 inches; at least 11.125 inches×8.125 inches×4 inches; at least 13.125 inches×10.125 inches×6 inches; at least 19 inches×8 inches×4 inches; or at least 21 inches×10 inches×6 inches. The thickness of the adjustable container 100 can range from about 0.05 in to about 5 in. For example, the thickness of the adjustable container 100 can range from a low of about 0.10 in, 0.25 in, or 0.5 in to a high of about 0.6 in, 0.8 in, or 3 in. It should be noted that although the depth of the adjustable container 100 is variable, both the length, L, and the width, W, can be fixed dimensions.

The adjustable container 100 can be made of paperboard, corrugated board, or any other suitable fiberboard or combinations thereof. For example, the adjustable container 100 can be made of cardboard, paperboard, or foam board. The board can be non-corrugated, corrugated, or a combination thereof.

In some examples, the adjustable container 100 can be a six-sided box that can be square, rectangular, non-square, or non-rectangular in shape. For example, the box can include at least four vertically oriented sides (e.g., 142, 144, 152, and 154), a top panel, and a bottom panel (e.g., 110). In some embodiments, the box can be polygonal in shape and can include 3, 5, 6, 7, 8, or more vertical sides. The adjustable box can further include at least two generally vertical delineations (e.g., 120) disposed on each corner (e.g., 101, 103, 105, and 107), and a least one delineation (e.g., 130) disposed in a second direction underneath any one of the vertical delineations 120 to provide a stop.

FIG. 2 depicts a perspective view of an illustrative panel board, blank, or box blank 200, according to one or more embodiments. The panel board 200 can be a sheet of corrugated board. The panel board 200 can have any number of scorelines or fold lines (four are shown 234, 236, 238, 240) formed thereon to facilitate folding and forming corners of the adjustable container. In one or more examples, the fold lines 234, 236, 238, 240 can be or can include a mark, an indentation, or a line disposed or located on, in, along, or otherwise about the panel board 200. The fold lines 234, 236, 238 240 can be formed by a groove, score, perforation, indentation, crease, or other suitable delineator disposed on, in, along or otherwise about the panel board 200.

The panel board 200 can further include one or more top flaps (four are shown) 212, 216, 232, 224; one or more bottom flaps (four are shown) 214, 218, 222, 226; and side panels (four are shown) 242, 244, 246, 248 that can form the sides of an assembled adjustable container. Each segment, section, side panel, end panel, or panel 242, 244, 246, 248 can be defined by a set of boundaries. For example, a first side boundary 208 and/or a second side boundary 210 can extend between an upper boundary 204 and a lower boundary 206. The first side boundary 208 and/or the second side boundary 210 can extend generally perpendicularly between the upper boundary 204 and the lower boundary 206. In some examples, one or more of the fold lines 234, 236, 238, 240 can extend between the upper boundary 204 and the lower boundary 206. As a result, the fold lines 234, 236, 238, 240 can, at least partially, define the one or more segments, sections, side panels, end panels, or panels 242, 244, 246, 248. For example, a first panel 242 can have an outer boundary defined by the first side boundary 208 and/or a first fold lines 234 and a second fold lines 236. A second panel 244 can have an outer boundary defined by the second fold lines 236 and a third fold lines 238. For example, a third panel 246 can have an outer boundary defined by the third fold lines 238 and a fourth fold lines 240. A fourth panel 248 can have an outer boundary defined by the fourth fold lines 240 and the second side boundary 210.

In some examples, the panel board 200 can include at least two sections or sets 220 of delineations 120 disposed along at least one fold line 234, 236, 238, 240. Each set or section 220 can include any suitable number of delineations 120. The number of delineations 120 can vary in each set 220 or each set 220 can have the same number of delineations 220. The number of delineations 120 in each set 220 can be, for example, 1 to 10 or more. When multiple delineations 120 are used, the delineations 120 can be arranged in series, arranged linearly or arranged at least in a generally straight line. In some embodiments, each delineation 120 can have a generally longitudinal axis oriented in a substantially perpendicular direction relative to the upper boundary 204 and the lower boundary 206 of the panel board 200.

As explained above, the second delineation 130 can be located and oriented at an angle beneath each set 220 of first delineations 120. The delineation 230 can be a straight line, curved, u-shaped or c-shaped so as to create a stop or resistance angle beneath the first delineations 120. The panel board 200 can also include at least one tab 250 that can be glued or secured by other means to an opposing side boundary (e.g., 210) to further secure a closed configuration of the adjustable container.

In some examples, the panel board 200 can have a size of at least 7.875 inches×27.75 inches, at least 9.875 inches×29.75 inches, at least 11.875 inches×31.75 inches, at least 12.375 inches×44.25 inches, at least 14.375 inches×46.25 inches, at least 16.375 inches×48.25 inches, at least 12.25 inches×59.75 inches, at least 14.25 inches×61.75 inches, or at least 16.25 inches×63.75 inches. In other examples, the size of the panel board 200 can be less than 7.875 inches×27.75 inches.

The panel board 200 can be made of one or more sheets, layers, or panels, of any suitable material, e.g., a fiberboard including paperboard, corrugated board, or any combination thereof. For example, the panel board 200 can be made of cardboard, paperboard, foam board, or other suitable material. A method for producing the panel board 200 can include cutting the panel board 200 from a larger sheet of material, or the panel board 200 can be assembled from a plurality of sheets of material.

The material for making the panel board 200 can include a single sheet or two or more layered sheets. The sheets can be flat, non-corrugated sheets, corrugated sheets, or a combination thereof. In one or more examples, the panel board 200 can be a corrugated linerboard made of a paperboard material having a first side, a second side, and a thickness determined by a distance between the first and second side. The panel board 200 can be a corrugated panel board that can include at least a first paperboard layer, a second paperboard layer, and a corrugated layer disposed between the first paperboard layer and the second paperboard layer. The corrugated panel board can include a first corrugated linerboard, a second corrugated linerboard, and a corrugated medium disposed therebetween. The corrugated medium can be bonded to the first and/or second linerboards by any suitable methods. For example, an adhesive can be used and located at the tips of the flutes of the corrugated medium to bond the first and/or the second linerboards to the corrugated medium.

In one or more examples, the material of the panel board 200 can have any suitable basis weight. In one or more examples, one or more adhesives can be disposed on the panel board 200 at any suitable location or combination of locations to provide, at least in part, adhesive bonding. For example, an adhesive can be disposed on the tab 250 and can be used to secure the first side boundary 208 to the second side boundary 210.

FIG. 3 depicts an isometric view of an illustrative assembled adjustable container 300, according to one or more embodiments described. As assembled, the adjustable container 300 can have four corners 301, 303, 305, 307. At least two sets 320 of delineations 120 can be formed in each corner. Each set 320 can include from 1 to 10 or more delineations 120 arranged in series. At least one second delineation 130 can be located underneath each set 330 of delineations 120.

FIG. 4a depicts a perspective view of the illustrative adjustable container 100 of FIG. 1 after the uppermost section, or at least one set of the delineations 120, has been separated down to an uppermost second delineation 130, according to one or more embodiments. In one or more examples, as shown in FIG. 4b , the top flaps 104, 106, and 108 can be folded along an uppermost, or a first, scoreline or folding line (e.g., see 174), while the top flap 102 can remain extended. For example, the opposing top flaps 106 and 108 can be folded inward, along the uppermost or first folding line (e.g., 174), toward one another, while the top flap 104 can be folded inward, along the uppermost or first folding line (not shown), toward the opposing top flap 102, and on top of the top flaps 106 and 108. Alternatively, if desired, excess material can be removed. As shown in FIG. 4c , the top flap 102 can remain extended, and can be folded along the first folding line 172 over and on top of the top flap 104. Moreover, depending on the desired size of the box, all of the flaps 102, 104, 106, 108 can remain extended. The reduced depth adjustable container 100 can then be sealed with a sealing tape or glue for completed assembly.

FIGS. 5a and 5b depict another perspective view of the illustrative adjustable container 100 of FIG. 1 after the two uppermost sections, or at least two sets of the delineations 120 have been separated passed the upper, second delineation 130A down to the lower, second delineation 130B, according to one or more embodiments. The top flaps 102, 104, 106, and 108 can be folded along the second level of folding lines (e.g., 176, 178). The opposing top flaps 106 and 108 can first be folded inward, toward one another, while the top flap 104 can be folded inward, toward the opposing top flap 102, and on top of the top flaps 106 and 108. As shown in FIG. 5c , the top flap 102 can be folded over and on top of the top flap 104. The reduced depth adjustable container 100 can then be sealed with a sealing tape or glue for completed assembly.

FIG. 6 depicts a perspective view of illustrative assembled adjustable containers 640, 650, 660 formed into three varying depths, according to one or more embodiments described. In some examples, the adjustable container 640 can be assembled without separating any of the first delineations 120. Depending upon the desired size of the container, upper set 620, or the uppermost section of first delineations 120 can be separated down to the upper most, second delineation 130 to make a smaller container 650. Or, both sets 630 or the two uppermost sections of first delineations 120 can be separated down to the lower most, second delineation 130 to make even a smaller container 660.
